Company Overview
Imagine a piloted air taxi that takes off vertically, then quietly carries you and your fellow passengers over the congested city streets below, enabling you to spend more time with the people and places that matter most. At Joby, we've been working to make that dream a reality since 2009 and we're now in the final stages of certifying our aircraft with the FAA. With plans to launch our aircraft in the US and Dubai, we're now scaling manufacturing and preparing for the launch of our commercial service.

Joby Aviation is seeking a passionate, motivated and hands-on Senior Test Engineer on the Electro-Mechanical Test Team to aid in characterization, performance, environmental and reliability testing of powertrain & electronics system comprising of electric motor, inverter and related systems and/or components. This role is a member of the Integrated Product Team (IPT) and leads the testing efforts on verification and validation testing activities for the propulsion systems with specific emphasis on Electrical-Thermal Stress testing and Electromagnetic Magnetic Effects Testing (such as HIRF, RF Emissions, Lightning).
Responsibilities
- Test preparation includes:
- Test engineering: Identify test objective(s), collaborate with design and system engineers to devise test matrices, instrumentation needs, and outline detailed test procedures
- Test article: Coordinate appropriate and configuration-controlled test articles to meet test objective(s)
- Test Equipment: Work closely with Test Equipment Design Engineers to have custom test rigs built, assembled, operated, and maintained. Key contributions are defining requirements and expectations of the test stand/test setup to Test Equipment Design Engineers
- Test execution includes:
- Outline test execution schedule to ensure test equipment and resources are available to meet test objective(s)
- Perform safe and thorough testing following Test engineering process to produce data that meet the needs of the program
- Review and analyze data collected during/after testing to generate reports that will provide quantifiable feedback to the engineering teams that will allow them to optimize their designs and/or show compliance towards certification
- Perform root cause investigation and analysis of sub-systems and components, documenting findings, and providing feedback to appropriate stakeholders for corrective action(s)
- Work closely with the Test Program Manager to plan assigned work, report status and progress, and ensure tests are properly documented and closed out to meet program objectives
